Friction Springs for Earthquake Protection

By Lars Jahnel on Jul 19, 2017

If buildings are shaken by earthquakes this can lead to cracks, instabilities in the support structure and in worst case szenarios to the collapse of the building. To efficiently absorb the enormous forces and thereby protect both, person and material, nowadays sophisticated technologies are available.

Not all damages that a great earthquake will cause can be avoided. However, with Friction Springs there is a very high probability, that the building withstands an earthquake – like those in Christchurch/NZ in 2010 and 2011 – and is still operational and habitable.

How does a Friction Spring Work?

By Lars Jahnel on Jun 21, 2017

In a previous article we covered friction springs and their applications. This time we would like to explain the technical properties of a friction spring, how it works and why its features provide a variety of advantages compared to other damping systems.

Friction Springs - Experts in the Field of Damping Technology

By Sophie Keil on Mar 22, 2017

Friction springs are indispensible safety components in all fields of technology where suddenly occurring forces have to be taken up and kinetic energy absorbed, or where springs are required with relatively compact dimensions while also being able to sustain high forces. Expert friction springs are needed when it comes to the deceleration of moving masses in a quick, safe and precise manner.

Elastomeric Materials – An Overview

By Simon Graf on Jan 04, 2017

Elastomers are polymeric materials which have the property of high elasticity. By virtue of this elasticity in combination with their damping capability, elastomers are the preferred material for use as transmission elements in elastic or highly elastic couplings. [1]

Mechanical Properties of Elastomers

By Simon Graf on Nov 30, 2016

One of the distinguishing properties of elastomers is their high elasticity. The main characteristics of elastomers present themselves, in particular when comparing them to steel. Below we would like to elaborate on the main properties of elastomers in more detail. Figure 1 shows the main characteristics of elastomers. They are able to combine spring properties as well as damping ability in one component.

Stiffness and Damping: This is what Engineers have to Consider when Tuning a Coupling

By Simon Graf on Jul 20, 2016

Stiffness describes the ability of a body to resist elastic deformation. The transmission of power would not be possible without stiffness. However, there are events which should not be transmitted, such as torque peaks and shock loads. In order for a system to withstand such loads, it is damped. Engineers are confronted with the challenge to tune stiffness and damping in a vibratory system in such a way that reliable operation, essentially free of load peaks, is ensured.

Sophisticated Technology in the Mars Rover Curiosity: Mission Damping Accomplished

By Lars Jahnel on Jul 04, 2016

The robust drill on the robot arm of the Mars Rover Curiosity helps scoop rock dust on Mars – a milestone for researchers. A friction spring made of stainless steel dampens the forces generated during the drilling process and prevents any resonance phenomena.
